Cardiome Pharma and Astellas Pharma U.S. Announce PDUFA Action Date Extended by Three Months

VANCOUVER, and DEERFIELD, IL, Aug. 30 - Cardiome Pharma Corp. and its co-development partner Astellas Pharma US, Inc. ("Astellas") today announced that the U.S. Food and Drug Administration (FDA) has requested that Astellas and Cardiome participate in a panel review to be conducted by the Cardiovascular and Renal Drugs Advisory Committee on December 11-12, 2007. The New Drug Application (NDA) for the intravenous formulation of vernakalant hydrochloride, an investigational new drug for the acute conversion of atrial fibrillation, will be reviewed as part of a two-day meeting regarding therapies for acute conversion of heart arrhythmias.

In preparation for the panel, and at the request of the FDA, Astellas has agreed to file additional information including final safety and efficacy data from the ACT 2 clinical trial, which was ongoing at the time of original NDA submission. As a result of this amendment to the NDA, the FDA has indicated that the action date under the Prescription Drug User Fee Act (PDUFA) will be extended by three months to January 19, 2008. It is expected that discussions related to the application review and labelling will continue with FDA throughout the intervening period.

The Cardiovascular and Renal Drugs Advisory Committee is convened on request of the FDA, and reviews and evaluates available data concerning the safety and effectiveness of human drug products for use in the treatment of cardiovascular and renal disorders and makes appropriate recommendations to the Commissioner of Food and Drugs. Although the Committee provides advice to the Agency and suggests a course of action, final decisions are made by FDA.

"Upon the acceptance of the NDA for filing in February, we and Astellas began preparation for an advisory panel, considering that vernakalant (iv) is a new chemical entity for the treatment of atrial fibrillation. We and our key clinical advisors welcome the opportunity to present our data on vernakalant (iv) to the Panel and the American public," stated Bob Rieder, Chief Executive Officer and Chairman of Cardiome. "Presentation of the program to the Advisory Committee is an important milestone in the NDA review before an action on the application from the FDA in January of 2008. Commercialization plans continue to move forward."

"Astellas, along with our co-development partner Cardiome, look forward to discussing the clinical safety and efficacy information for vernakalant (iv) with the Cardiovascular and Renal Drugs Advisory Committee, as a part of an overall dialogue on new pharmacological therapies for acute conversion of atrial fibrillation," stated Yoshihiko Hatanaka, President and Chief Executive Officer at Astellas. "The data from the ACT 2 trial offers both the FDA and the Advisory Committee additional insight regarding vernakalant (iv) as a potential new treatment option."

The NDA for vernakalant (iv), based on a 5-year clinical development program, was submitted in December 2006 and accepted for review by the FDA in February 2007. Upon approval, vernakalant (iv) will be marketed in the United States by Astellas Pharma US, Inc., a U.S. affiliate of Astellas Pharma Inc. In October 2003, Cardiome granted Astellas Pharma US, Inc. an exclusive license to develop and commercialize vernakalant (iv) in North America. The companies have co-developed vernakalant (iv) to NDA, with Astellas responsible for 75% of development costs. Cardiome has retained all rights to the intravenous formulations outside of Canada, U.S. and Mexico.

About Cardiome Pharma Corp.

Cardiome Pharma Corp. is a product-focused cardiovascular drug development company with two late-stage clinical drug programs focused on atrial arrhythmia (intravenous and oral dosing), a Phase 1 program for GED-aPC, an engineered analog of recombinant human activated Protein C, and a pre-clinical program directed at improving cardiovascular function.

Vernakalant (iv) is the intravenous formulation of an investigational drug being evaluated for the acute conversion of atrial fibrillation (AF). Positive top-line results from two pivotal Phase 3 trials for vernakalant (iv), called ACT 1 and ACT 3, were released in December 2004 and September 2005. Cardiome's co-development partner Astellas Pharma US, Inc. submitted a New Drug Application for vernakalant (iv) in December 2006. Positive top-line results from an additional Phase 3 study evaluating patients with post-operative atrial arrhythmia, called ACT 2, were released in June 2007. An open-label safety study evaluating recent-onset AF patients, called ACT 4, has completed.

Vernakalant (oral) is being investigated as a chronic-use oral drug for the maintenance of normal heart rhythm following termination of AF. Cardiome announced positive results from a Phase 2a pilot study for vernakalant (oral) in September 2006. A Phase 2b study for vernakalant (oral) is ongoing.

In April 2007 Cardiome acquired exclusive worldwide rights for GED-aPC for all indications. Cardiome intends to initially develop GED-aPC in cardiogenic shock, a life-threatening form of acute circulatory failure due to cardiac dysfunction, which is a leading cause of death for patients hospitalized following a heart attack.

Cardiome is traded on the Toronto Stock Exchange (COM) and the NASDAQ National Market (CRME).
